24 amazing innovations from rural India

India's rural innovators have proved that ordinary people are indeed capable of extraordinary inventions. Despite many constraints -- lack of education and severe cash crunch -- most of them have succeeded in using technology cost-effectively to build ingenious products. A washing-cum-exercise machine, hand operated water lifting device, portable smokeless stove, automatic food making machine, solar mosquito killer, shock proof converter, a floating toilet soap are few of the products on display at the exhibition of grassroots innovations at the Rashtrapati Bhavan.

President Pratibha Patil inaugurated the three-day exhibition at Rashtrapati Bhavan on Monday. The exhibition has been hosted at Rashtrapati Bhavan since 2010, as the President wished to give grassroots innovators, a platform to showcase their amazing innovations.

The exhibition is organised by the National Innovation Foundation (NIF), a grant-in-aid institute under the Department of Science and Technology (DST) set up in February 2000.

The mission of NIF is to make India a global leader in sustainable technologies by building upon genius of grassroots technological innovators and traditional knowledge holders.

Bhagwan Singh Dangi (Reaper windrower machine)
Madhya Pradesh

Many times, in a standing crop, soybean pods shatter due to non-availability of labourers for harvesting the crop in time, leading to reduced yield and loss. To solve this problem Bhagwan Singh decided to develop a reaper windrower machine.

This device has three different units namely, cutting unit, which consists of cutter bar, reel unit for pushing the standing crop towards the cutter bar and gathering unit to windrow the crop at centre of the machine thus making it easy to handle/transport to the threshing floor. It reduces manpower requirement and the drudgery involved in the harvesting process. The machine has 7 ft width of operation and can cover 0.4 hectares per hour. While operating this machine, fuel consumption of tractor is 2.5-3 litres per hour.

N Sakthimainthan (Hand operated water lifting pump)
Tamil Nadu

Sakthimainthan built his hand operated water pump in response to a dearth of available pumps that could be afforded by small farmers.

He built five prototypes over a period of fifteen years before finally perfecting his design.

The resulting water-lifting device is operated by the continuously rotating a handle. It is simple in design and has a high discharge at low cost compared to the motorized pumps and conventional hand pumps.

The pump has discharge of 20,000 lph at 0.75 m head. The unit has also been tested by TNAU, Coimbatore and improved by CMERI Durgapur. It is useful device for drainage as well.

Radhey Shyam Sharma (Bullock operated sprayer)
Madhya Pradesh Bhanjibhai Mathukia
Gujarat

The bullock operated sprayer is pulled by a pair of bullocks and gets the drive from the ground through a gear box and belt pulley system.

When the operator shifts the lever to a higher gear, the frequency of strokes of the pump increases as a result of which more pressure develops in the container. The spray fluid, thus, atomizes into fine droplets with a wider swath. This sprayer considerably reduces time requirement as compared to manual spraying and also the drudgery and health hazards involved in manual spraying. It has 18 nozzles, spaced at a distance of 35 cm and can cover 3.5 acre/h.

M. Nagarajan (Lemon cutter)
Tamil Nadu A small workshop owner from Uslampathy village in Tamilnadu, M Nagarajan has developed an innovative technology for cutting lime into small pieces in bulk quantity. This technology offers a great value proposition for the pickle manufacturing companies. The pickle industry suffers with a big problem of inefficiency in its operations due to low degree of automisation e.g. cutting of fruits is done manually. The second big problem, the industry faces is short-supply of labour during peak seasons, which limits the capacity. It is a novel machine in terms of its cost effectiveness, efficiency, drudgery reduction for women, safety considerations and transmission system.

P K Ravi (Pepper thresher)
Kerala

As compared to other conventional threshers, Ravi's thresher can be operated both automatically and manually with higher output and minimal damage.

Gurmeel Singh Dhonshi (compost Aerator & leaf pruner)
Rajasthan

Decomposed bio-waste has better fertility values. Decomposition can be fastened if the biomass is aerated, humidified and properly mixed.

Dhonshi's machine is a tractor PTO driven machine, which can thoroughly mix the bio-wastes and add moisture as well thereby reducing the time of decomposition.

The machine can cover a row of wastes disbursed by 100 trailers of size 11 ft x 6.5 ft x 2.5 ft (i.e total 400 ton) in one hour. Tractor consumes 3.5-4.0 liter diesel per hour. The compost has better fertility value as compared to FYM and vermin compost.

Total time for converting the biomass into manure while processed by this machine is 25-40 days, which is otherwise 3-4 months by the conventional methods.

Swayambhoo Sharma, Madanlal Kumawat, Chandan Agarwal
(Modified hand pump with tap and attachment for filling animal trough) Rajasthan/Delhi

Lack of surface water sources and falling water table has made availability of clean drinking water a major problem in Rajasthan.

For human beings, the need gets addressed to some extent but for animals this need is much less appreciated.

Swayambhoo Sharma came up with an interesting solution to address the drinking water needs of animals.

He developed an arrangement such that every time people pump water for their use, 20 per cent of pumped water will directly go to fill animal water trough. Since most people feel lazy in filling drinking water trough for stray animals, this innovations solves this problem by a kind of tax at source.

Another problem faced in hand pumps is that a single person finds it very difficult to pump and at the same drink water (without a vessel with him/her).

Chandan, then a first year student at IIMA came out with an idea of storing water in the body of the hand pump so that having pumped, one could use a tap and drink water like any other tap.

Yusuf Khan and Madan Lal Kumawat, two other innovators combined the idea of Chandan and Swayambhoo Sharma and developed a hybrid model.

Raghav Gowda (Milking machine) Karnataka

Finding skilled labour for milking a small herd of cows is a problem faced by many farmers.
